Data Reporting System - Theme: Inland waters
Introduction
Inland waters is one of the four physical spheres of the Earth's environment, along with the atmosphere, the land and coasts and oceans.
The issues included in the Inland waters theme have been structured to reflect the conceptual model used in the National Land and Water Resources Audit's Assessment of River Condition (ARC), which had a focus on biological (aquatic ecosystem) outcomes and indicators. It includes condition and pressure issues at the catchment level, the habitat level and the biota level. Societal responses to pressures or deteriorating conditions are examined as separate issues because of the time lag before responses can be expected to translate into improvements in condition or reductions in pressures.
Issues
Catchment scale influences
- Influence of climate variability and change
- Hydrological condition
- Land and vegetation condition
Habitat scale influences
- In-stream habitat - woody debris and sand slugs
- Riparian vegetation
- Wetlands
- Fish passage
- Water Quality (for surface and groundwater)
Response of biota
- Bacteria and algae
- Macroinvertebrates
- Fish
- Frogs
- Waterbirds
- Wetland and floodplain communities
- Invasive species
- Stream metabolism
Human response - policy and management
- Management of surface and groundwaters
- Environmental flows allocation and management
- Habitat management (including wetland management)
- Management of aquatic biota and biodiversity
